Bartosz Waszak Trading AS Hosteam S.C. Tomasz Groszewski Bartosz Waszak Lukasz Groszewski

BARTOSZ WASZAK TRADING AS HOSTEAM S.C. appears in public routing registries as a Poland-based hosting network operator (RIPE region). The AS name explicitly lists Tomasz Groszewski, Bartosz Waszak, and Lukasz Groszewski; beyond that, publicly consistent corporate details are limited and fragmented.

The organization is associated with ASN AS51290 (registry: RIPE) and is labeled as “Hosting” by multiple IP intelligence datasets. Public netblock listings commonly include 31.133.0.0/21, 178.217.184.0/21, several /24–/23 IPv4 ranges (e.g., 91.206.26.0/24, 91.224.220.0/24), plus IPv6 prefixes such as 2001:67c:d94::/48 and 2001:67c:2044::/48; upstreams are reported as Arelion (AS1299) and Netia (AS12741).

Direct end‑user service reviews are scarce in widely indexed review platforms, so a confident reputation score is hard to justify. Some risk-scoring and abuse-report aggregators flag portions of observed traffic from this network as medium risk, but that is not equivalent to verified customer feedback.
